Republic of Ireland international Quinn has been forced to undergo surgery on the knee problem which has seen him sidelined since the win at Bristol City and is not expected to return until the New Year.

And Robson-Kanu, who injured his ankle while on international duty for Wales, may not return until December at the earliest.

Royals boss Steve Clarke said: “Stephen won’t be with us probably until end of December or January.

Hal Robson-Kanu impressed.

“He’s had an operation that we were hoping we could avoid. But he’s had to go in and have surgery and we’re now looking at maybe 10 weeks from now until he’s back.

“It’s a blow for Stephen. But he’ll work diligently on his rehab and get himself ready.

“His wife is also expecting a baby any day now so he’s going to be busy these next few weeks.”

Clarke added: “There’s also bad news on Hal. He doesn’t need an operation but it’s an injury which will probably keep him out for between six to eight weeks.

“So it’s been a bit of a blow to us with those two bits of news.

“But it gives others a chance. We brought a lot of good players to the club in the summer so it gives them a chance to make a contribution to the season and help us pick up more points before the two boys come back.”
